Documentation is much more than just commenting code. It can be a lot more fun too. Learn what types of documentation are useful, when it is appropriate to use and how to write it. Through real-world examples, this talk will teach you how to create meaningful and helpful documentation. Not just for posterity, but to guide you in your development efforts. about this event: http://programm.froscon.d...

Clojure is a JVM-based functional language with special features that achieves the impossible: a practical Lisp, usable by mere mortal developers. In this session we'll first cover some Clojure basics and then show how to efficiently develop web applications using a set of open source libraries. about this event: http://programm.froscon.de/2012/events/1046.html

Platform technology: "... is a term for technology that enables the creation of products and processes that support present or future development." [1] This talk will present obvious and non-obvious challenges for an Embedded Linux project and provide mechanisms and strategies to counter these. Obvious issues include how to maintain system robustness e.g. upon power failure during a partially writ...

It is nearly impossible to go online today without stumbling upon Wikipedia at some point along the way. Wikipedia, however, is just one of several projects in the Wikimedia movement next to Wikimedia Commons, Wiktionary and more. In April a team of 12 started working on the foundations of a new Wikimedia project for 1 year. The project is called Wikidata. The goal is to provide Wikipedia and the...

Domain Specific Languages (DSLs) can enhance many projects, as just a powerful configuration format, a way to conveniently customize your app for different use cases or to ease communication with non-developers in your team. about this event: http://programm.froscon.de/2012/events/1028.html

eAnalytics ist ein Open Source Webanalyse-System, das die Integration von Daten aus unterschiedlichen Datenquellen unterstützt und eine enge Integration mit anderen Systemen (CRM, Data Mining, Data Warehousing etc.) ermöglicht. In dem Vortrag wird das Webanalyse-System eAnalytics mit seinen besonderen Eigenschaften im Detail dargestellt. Der Vortrag richtet sich sowohl an Unternehmen, die Interess...

Since the PHP core and the extension API are implemented in C, most PHP extensions are written in C, too. But it is possible to write extensions using the C API and a C++ compiler. This has the advantage that you can use all the nice features of C++, like object orientation, exceptions, templates and the STL. Apart from using these features in the extension code, they can also be used to wrap part...

The world needs Free devices. KDE's Plasma team has set out to deliver a device that is Free, open and hackable, and which puts the user in full control of its hardware and software. about this event: http://programm.froscon.de/2012/events/1019.html

With the release of the Kinect device, there was finally an affordable camera capable of giving depth information. This, together with the Kinect's open USB connection, led to a lot of innovative projects. Still, the Kinect just gives raw signals and the only way to obtain more complex information, such as skeleton tracking was to use either the Microsoft SDK or the OpenNI framework. Both of these...

Aldebaran Robotics is the creator of the NAO robot that runs Linux. We think a lot of Linux users are interested in knowing more about it. Moreover we are committed to share some of our source code and are already sharing five public repositories in Github. Über den Autor Akim Boukhelif: Akim Boukhelif is a member of the NAO developer program team working at Aldebaran Robotics where our famous NAO...

While everything is pretty much said and done on the x86 graphics front, and all the players have taken their respective positions and stick by it (despite ones best efforts), nothing has been done for the ARM world, even with the massive market penetration the linux and ARM combination currently has. The Mali is ARM's own GPU that is rapidly gaining traction. The most popular high end android sma...

Wir sind die Part-Time-Scientists und sind dabei einen Rover zum Mond zu schicken. Der Kamera Prototyp unseres Rovers ist an einen Nvidia Ion Mini ITX Board angebunden. In kurzer Zeit entstand ein in Qt geschriebener Webserver, der die Bilder von einem V4L2 Interface mit OpenCL verarbeitet und komprimiert über Websockets über WLan an einen Browser verschickt. Zur Kontrolle dient ein leicht modifiz...

Modelleisenbahnen sind heute eine extrem digialisierte Geschichte, bei der das Gleis sowohl die Betriebsspannung liefert als auch als Datenbus zu den Loks dient. Wenn man eine Märklin-Bahn mit dem Rechner oder dem Handy steuern möchte, braucht man zusätzlich zu Gleisen und Rollmaterial Digital-Equipment für 500-1000 Euro aufwärts (Central Station, Router, iPhone). Der Vortrag stellt eine Alternati...

A vast majority of new Embedded System projects make use of the Linux Kernel. Unfortunately, neither the development process nor the quality assurance process of the Kernel are fully understood by many companies. Often, buggy vendor kernels from board support packages are preferred over a standard mainline kernel although the latter has passed the complete review process while the kernel suppied b...

Bei der Beurteilung der Frage, ob kritische Infrastrukturkomponenten wie IT-Basisdienste oder sensible Daten insbesondere in Public Clouds verlagert werden können, verhalten sich viele IT-Entscheider noch konservativ. Wichtiger Grüde dafür sind fehlende Integration der Cloud-Angebote unterschiedlicher Anbieter, ungelöste rechtliche Probleme und vor allem die Sorge, sich hier durch proprietäre Tech...

Wikidata is a new project for Wikimedia. Wikidata aims to create a free knowledge base about the world that can be read and edited by humans and machines alike. It will provide data in all languages of the Wikimedia projects, and allow for the central access to data in a similar vein as Wikimedia Commons does for multimedia files. It will help take Wikipedia to the next level and provide the world...

Die Cloud verspricht Flexibilität, Skalierbarkeit nach Bedarf, und die Reduzierung von Kosten und Aufwand für die Wartung von Server-Systemen. Prominente Erfolgsgeschichten wie Amazon oder Google scheinen dieses Versprechen zu bestätigen. Aber in der Praxis ist der Weg in die Cloud oft noch steinig. In dieser Präsentation werden wir unsere Erfahrungen berichten, wie es gelingen kann, erfolgreich d...

OpenStack ist die vielversprechendste Lösung für Unternehmen, die eine eigene Cloud aufbauen wollen. Die Umgebung bietet alles nötige, damit die Wolke kein Luftschloss bleibt: Nova kümmert sich um die Verwaltung der Ressourcen und um das Starten neuer virtueller Instanzen, Glance verwaltet Betriebssystem-Images und Swift bietet objekt-basiertes Storage. Das OpenStack-Dashboard namens Horizon ist d...
